Subject: Updated C++ standard to C++17

C++17 should be universal enough by now.

This raises the minimum CMake to 3.8, which should also pose no problem since
Ubuntu 18.04 already shipped with CMake 3.10.

C++17's 'if' initialization statement is now used in an efficient
implementation of 'join' for vector<string>, found on StackOverflow.
